True if you can not measure the timings but such bashing engines have enough room to work on.
Sending it over to someone who does some polishing, edging and teardrops for lots of money is indeed a choice.
Just some touching on all edges with a dremel to stretch all tolerances on the timings can do a lot w/o harming the engine as long you smoothen out all sharp edges from the touched ports.
